Access Control

This section introduces methods for controlling access to the database, graphs, and data.

Privilege

ShowPrivilege()

Retrieves all system privileges and graph privileges.

Parameters

• config: *configuration.RequestConfig (Optional): Request configuration.

Returns

• []*structs.Privilege: A slice of pointers to the retrieved privileges.
• error: An error object that contains details about any issues encountered during the operation. If the operation succeeds, nil is returned.

Go
// Retrieves all system privileges and graph privileges

response, _ := driver.Uql("show().privilege()", nil)
privileges, _ := response.Alias("_privilege").AsPrivileges()

var graphPrivileges []string
var systemPrivileges []string

for _, privilege := range privileges {
    if privilege.Level == structs.GraphPrivilege {
    	graphPrivileges = append(graphPrivileges, privilege.Name)
  	} else {
    	systemPrivileges = append(systemPrivileges, privilege.Name)
  	}
}

fmt.Println("Graph Privileges:", graphPrivileges)
fmt.Println("System Privileges:", systemPrivileges)
